When you first spot a serpae tetras, it’s hard not to be captivated. Their vibrant, fiery red bodies and active personality light up any tank like a tropical flame flickering in the water. But behind their beauty lies a fascinating character, one that every aquarist should understand before adding to their collection.
In this comprehensive guide, we’ll dive deep into everything you need to know about caring for the bold and brilliant serpae tetra, from tank setup and feeding to behavior, breeding, and compatible tank mates.
Also known as the Red Minor Tetra or Jewel Tetra, the serpae tetras (Hyphessobrycon eques) is a freshwater species originating from South America, particularly the Amazon River basin.
- Size: Up to 1.75 inches (4.5 cm)
- Lifespan: Around 5 to 7 years
- Color: Bright red body with a distinctive black comma-like spot near the gills
- Personality: Energetic, sometimes nippy
While they’re visually striking, they’re also known for a semi-aggressive streak, especially when kept in small numbers. Thankfully, with the right care and tank environment, that behavior can be easily managed.
Why Choose Serpae Tetras for Your Aquarium?
Adding a splash of red and a burst of movement, serpae tetras can become the star of your tank. Here’s why many aquarists adore them:
- Highly active: Constantly on the move, they bring your tank to life.
- Eye-catching color: Their rich red hues contrast beautifully with green plants.
- Hardy nature: Ideal for both beginners and experienced hobbyists.
However, their best qualities shine when their care is tailored to their social and environmental needs. That means creating a balanced tank where their behavior complements, not clashes.
Ideal Tank Setup for Serpae Tetras
Creating a suitable environment is crucial for the happiness and health of your serpae tetras. Let’s explore the essentials:
Tank Size and Schooling
- Minimum tank size: 20 gallons
- Best kept in schools of 6 or more to reduce aggression
Environment
- Temperature: 72-79°F (22-26°C)
- pH: 5.5 to 7.5 (slightly acidic to neutral)
- Water hardness: Soft to moderately hard (5-20 dGH)
Aquascaping Tips
- Dense planting helps diffuse aggression and offers hiding spots
- Include driftwood and natural-looking decorations for aesthetics and comfort
- Use a dark substrate to enhance their colors

Feeding Your Serpae Tetras
Like all tropical fish, serpae tetras thrive on variety. A well-rounded diet not only enhances their color but keeps them healthy and energetic.
Daily Diet Includes:
- High-quality flakes or micro-pellets as a staple
- Frozen or live foods like bloodworms, daphnia, or brine shrimp
- Occasional vegetable matter such as spirulina flakes
Feed small portions 2-3 times a day. Avoid overfeeding, as uneaten food pollutes the water, leading to health issues.
Understanding Serpae Tetra Behavior
Serpae tetras are known for their spunky personalities, but they can be misunderstood. Their tendency to nip fins isn’t a sign of aggression—it’s more of a social behavior.
Behavioral Traits:
- Semi-aggressive when kept alone or in small groups
- Calmer in larger schools where pecking order is established
- Tend to chase or playfully nip slower fish with long fins
To manage this, always keep them in a proper school. Think of them like a lively group of teenagers—when alone, they might act out, but in a group, they stick to each other and keep the peace.
Best Tank Mates for Serpae Tetras
Serpae tetras can live peacefully with other species when chosen wisely. The trick is avoiding slow or long-finned tank mates that might be targets of nipping.
Good Companions:
- Corydoras catfish
- Platies and mollies
- Larger tetras like black skirts or bleeding hearts
- Barbs (non-aggressive types)
Avoid:
- Betta fish
- Angelfish
- Guppies with long fins

Breeding Serpae Tetras
Breeding serpae tetras is quite doable with the right setup. In fact, it’s a rewarding experience for aquarists looking to grow their own school.
Breeding Setup:
- Separate breeding tank with sponge filter
- Soft, slightly acidic water (around pH 6.0)
- Temperature around 80°F (27°C)
Spawning Process:
- Add a conditioned male and female pair in the evening
- They scatter eggs among plants or spawning mops
- Remove adults post-spawning to protect the eggs
Eggs hatch in 24-36 hours. Start feeding the fry infusoria or commercial liquid fry food, then progress to baby brine shrimp.
Common Health Issues and Prevention
While generally hardy, serpae tetras can face health issues if their tank isn’t well-maintained. Prevention, as always, is better than cure.
Watch Out For:
- Fin rot (especially if there’s excessive nipping)
- Ich (white spot disease)
- Swim bladder disorders
Preventive Measures:
- Regular water testing and weekly 25% changes
- Don’t overcrowd the tank
- Quarantine new fish before adding to the community

Aquarium Maintenance for a Healthy Serpae Tetra Habitat
Keeping your tank clean is the backbone of any successful fish-keeping journey. For serpae tetras, clean water equals vibrant color and active behavior.
Weekly Tasks:
- Water change (20-30%)
- Test for pH, ammonia, nitrites, and nitrates
- Clean glass and remove algae
Monthly Tasks:
- Gently rinse filter media in tank water
- Trim and replant aquatic plants
- Deep clean decorations if needed
